COMPOSITION AND BURNISHING LUBRICANT.

SPECIFICATION formingpart of Letters Patent No. 267,994, dated November 28, 1882.

Application filed May 18, 1882. (No specimens.) I

To all whom it may concern:

Beit known that I, GEORGE S. BOUTWELL, a

citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a. new and use- -ful composition of matter to be used in the process of rolling or drawing metal in bars, rods, wire,in sheets, strips, or tubes, sothat the same will be prod ucedbrightly burnished or polished, and coated, if desired, with gold or other metal at less cost. and with less labor in producing than heretofore. I

My composition consists of the following ingredients, combined in the proportions stated, viz: sixteen parts tallow or other grease, four parts hard or other soap, one-sixteenth part (more orless, as desired) of gold, silver, or other wished-for metal in powdered form, and oneeighth part of oil, (lard-oil preferred.) These ingredients are to be thoroughly heated and mingled by agitation, the agitation to cease as the composition cools and hardens.

In using the above composition the wire, bars, rods, sheets, strips, or tubing of metal should first be well cleaned, so as to be free from all scales, dirt, sand, and other impurities on the surface. The metal to be burnished, or burnished and coated with gold, silver, or other metal in the composition, is then drawn through draw-plates or rolled or pressed in the usual manner, my composition being used as the burnishing-lubricant in connection with the metal to be burnished, or burnished and coated, by passing the article to be produced through my burnishing composition, or in any other manner applying the same as a coating to the metal as it passes through the pressure, draw'plates, or rollers.

I am aware that soap and tallow or other grease have been used as lubricants in drawing wire; butI am not aware that all of my ingredients in my composition have ever in any way been used together as a burnishing composition in drawing or rolling, and at the same time burnishing or polishing and coating with some other metal the metals drawn, rolled, or pressed.

What I claim, and desire to secure by Letters Patent of the United States, is

l. The burnishing composition herein described, applied for burnishing, or burnishing and coating, other metals with gold or suchv metal as may be desired, by drawing, rolling, or pressure in anymanner.

2. The combination of any lubricant with metal and the application of the same for the purpose of burnishing, or coating and burnishing, the metals operated upon by friction, roll ing, or pressure of any kind, substantially as hereinbefore described.

GEORGE S. BOUTWELL.
